Fanfictions can also explore the emotional states of the characters more deeply, such as GLaDOS' possible feelings of loneliness despite being a powerful AI.
Juliana Crain could be a main character. Her strong will and ability to see through the lies of the alternate reality could help her in the portal war. She might be the one to figure out how to close the portals or use them to the advantage of the resistance.
